Section 1: Project Overview

YouTube is the largest video sharing and hosting website nowadays. It has profoundly influenced people’s daily life, including the way of receiving and sharing information on a worldwide scale. Therefore, analyzing YouTube dataset becomes significant for companies to get an insight into how social media trends have a significant impact on changing the traditional way of advertising commercial products or build a brand recognition through the embedded advertising in a new form in YouTube videos. With that, we can make a prediction, which will be used for mapping out the future strategic business planning and resource mobilization.

Our overall objectives are investors and advertisers. We will provide business recommendations for these two types of users, including which channels have more business value and what topics people are interested in now.

We provide buesiness recommendations or advertisor and investor by the following steps:

  1. Identify the channels that created the most trendy videos in the past.
  2. Quantify the value of each channel on a scale from 1 to 10 and sort channel rankings by number of trendy video.
  3. Sort the channel with the least like-dislike ratios.
  4. Sort the channel by how long it takes to become trendy on average by using the time series.

Research Questions

  1. For each category, how long it takes, on average, for a video to become trendy?
  2. The total views of each of the top 10 channels in the first two quarters in 2018?
  3. For each category, how long it takes, on average, for a video to become trendy?
  4. For the United states and the Great Britain, the users like which category's videos most?
  5. Which keyword of channels will lead itself to become to have the most trending videos？

Section 2: Milestones and Progress

We finished our data cleaning step and data processing step, we also find appropriate dataset for our data. Therefore, we meet our milestones which is data cleaning.

Section 3: Data Acquisition and Cleaning Code (Markdown + Code)

Please provide code that demonstrates that you have made progress with data acquisition and cleaning. In a markdown cell at #### the top of the section, summarize what you have accomplished thus far.

Data Processing First of all,in the dataset, we need to use an extra category_dictionary.json file to index the real category of each video. Then there are two columns have datetime value but not format as datetime, so we convert it to datetime. We check the dataset and NAs, and there are several rows with only ‘video_id ’ exist but other columns show as NAs, so we simply delete these rows. Then there are still some NAs existing in ‘Description’ but that is due to the restriction by channels and that will not affect later analysis so we keep it in our dataset. In addition, there are some 0 between these numeric variables, but in general these cannot be 0, so we will check what happen to them, and we found restriction on these attributes.

  • Dropped null values generated during scraping and corrected time format
  • Pair the category ids with their names for further analysis
  • Dropped useless columns and removed unknown values which are shown as 0 in the data

Correlation between dataset variables

Now let's see how the dataset variables are correlated with each other: for example, we would like to see how views and likes are correlated, meaning do views and likes increase and decrease together (positive correlation)? Does one of them increase when the other decrease and vice versa (negative correlation)? Or are they not correlated?

Correlation is represented as a value between -1 and +1 where +1 denotes the highest positive correlation, -1 denotes the highest negative correlation, and 0 denotes that there is no correlation.

Let's visualize the correlation table between our dataset variables using a heatmap.

In [36]:
h_labels = [x.replace('_', ' ').title() for x in 
            list(you_df.select_dtypes(include=['number', 'bool']).columns.values)]
